2.2.7
Mode no. 7: parallel all bridges - one unidirectional DC motor
This mode, with all output power in parallel, allows driving a single-brush unidirectional DC
motor.
The motor supply voltage is connected to J1 pin 5 and 6 with a maximum voltage of 50 V
DC.
Maximum current is 11.2 A rms and the output R
DS(on)
is equal to 0.075 Ω (T
J
= 25 °C).
The maximum overcurrent detection threshold is set to 22.4 A.
